Bilinguals sometimes code-switch between their shared languages. While psycholinguistics research has focused on the challenges of comprehending code-switches compared to single-language utterances, bilinguals seem unhindered by code-switching in communication, suggesting benefits that offset the costs. I hypothesize that bilinguals orient their…

Noise is a common impedance to easy and accurate speech understanding. In the presence of noise, speech processing mechanisms proceed with partial or ambiguous inputs, and listeners will engage additional cognitive resources to make sense of what they hear. The extent to which this is situation is affected by diminished exposure to a language is…

Most of the world's languages include multiple varieties and dialects. Individual ability to successfully alternate between these varieties can be a socio-cultural and academic necessity for many bilingual speakers, including children in the US who alternate between African American English (AAE) and Mainstream American English (MAE). This…

Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

Across three experiments, the current study explored how accented speech and coarticulation impact how bilingual listeners comprehend code-switches in speech. Eye-tracking methodology was used to compare responses to single-language and code-switched sentences. Experiment 1 observed how accented speech influenced the costs involved in…

Bilingual psychologists serve the needs of the increasingly diverse US population, yet research suggests the training they receive to deliver bilingual or non-English clinical services is lacking, and many report feeling unprepared to deliver these services (Castano et al., 2007; Verdinelli & Biever, 2009a). The aims of this study were to a)…

This study investigates the role of prosody in narration as a function of Labovian narrative structure and stancetaking in identity performance. This study is both an extension and enhancement of preliminary work that looked at a handful of prosodic features in Mexican Spanish narratives, and a novel investigation into discursive acts expressed…

Accurately identifying developmental language disorder (DLD) in students who speak a home language other than English has proven to be an enduring challenge. Consequently, students with DLD miss out on critical interventions, and those who are acquiring their two languages in a typical manner are placed in settings that do not meet their…

The purpose of this study was to understand the phenomena of bilingual counselors who work with the Latinx/e population and provide counseling services using the Spanish language. Specifically, this researcher hoped to highlight the voices of recently graduated bilingual counselors who graduated within the last 5 years from CACREP programs and…

This dissertation outlines three studies investigating linguistically diverse students' (including bilingual and monolingual students) language use and self-efficacy in writing. Bilingual students are those who speak a language other than English, including students with various levels of English proficiency and language experience. The first two…

This dissertation investigates the extent to which bilingual speakers' cognitive representations of the syntactic structures of their two languages are interconnected. This is a substantially understudied domain despite the widespread existence of bilingual/multilingual communities in the world, including the US. To draw solid conclusions about…

Current speech-to-speech translation systems face challenges in effectively translating the nuances of prosody, which plays a pivotal role in conveying speaker intent and stance in dialog. This limitation restricts cross-lingual communication, especially in situations demanding deeper interpersonal understanding. To address this, this research…

Immigrant parents are being challenged in several different ways to maintain their heritage language (HL) in the United States. Majority White, affluent communities are one of the many complex language ecologies that exist across the variety of U.S. societies. The research setting of this study, Southern California, is one of the wealthiest…

This explanatory sequential mixed methods study explored how and why dual language (DL) teachers used technology and the extent to which their use of technology supported the goals of DL of bilingualism, biliteracy, academic achievement, and sociocultural competence. The study was guided by Mishra and Koehler's (2006) technological pedagogical…

Code-switching (switching between languages) is a common linguistic behavior in bilingual speech directed to infants and children. In adult-directed speech (ADS), acoustic-phonetic properties of one language may transfer to the other language close to a code-switch point; for example, English stop consonants may be more Spanish-like near a switch.…
